I spend some time to make a custom insert for Terraforming Mars, I just dislike all those tiny baggies! Everything fits neatly into the box and I just love the boxes for the Gold, Silver and Copper resources. Its so satisfying to align them all inside :D. I also enjoy that the cards are at an angle, makes shuffling unnecessary because you can just pick a card at random. Really happy how these came out.
From a Google ther appear to be at least 4!
